The lower end of the plun- Motion is imparted to thedriving-gear of ger-rod d carries two pivoted levers g, each the machineeither by the hand-wheel A or bearing rollers fand t' at their upper-andby suitable power pulley or gearing, and from lower ends. When theplungerb has reached 95 the main shaft B rotary motion'is transmittedthe bottom of the mold Fand the rod d proby bevel gear-wheels C- and Dto the gearingceeds farther down,by compressing the spring wheel q,Figs. a and 5, which through the e the rollers f will bear againstthe'inclin'ed medium of links m n o and connecting-rod guide-,surface hof the frame, whereby the p imparts intermittent rotary motion atregnlower arms of the levers g and the rollers 'i roo lar intervals tothe main work-table at, supare forced inwardly and engage the sliding 5oported upon the frame 17. The said workblocks k, pushing the same towardthe mold table carries four sets of molds and folding F, thereby closingthe ends of the mold withmeans, each set beinga counterpart of the inthe wrapper, and when this has been accomplished the rod d commences toretrace its course. I'Vhen the lower side of the plunger b reached thebottom of the mold F., the spring e Was compressed, and now as the rod dbegins to move upward theplunger b remains in its lowest position andforms an abutment for the sliding blocks 7a until the rollers i arecarried out of engagement with the blocks. When the plunger h has beenwithdrawn from the mold, the work-table a is turned one-quarter of arevolution, and thereby the mold, lined upon its sides with the wrapper,is brought into position below the filling-tube fr, from which at thepropel' time the exact quantityof matter required for one parcel isdischarged into the mold.

The measuring and discharging of the proper quantity to be packed isperformed in the following manner: The matter to be packed is containedin the hopper s, Fig. 2, from which it falls into one of thecompartments of a rotating drum u, to which onehalf revolution isimparted by a connectingrod t', hinged to the lever o, Fig. 4 The saidfilled compartment j after the half-revolution of the drum u is placedexactly over the feedtube 0, from which the matter falls into the moldF, lined upon its two sides with the wrapper. After the contents of thecompartmentj have been discharged into the mold the work-table a isturned into position III, and during the passage from position II intoposition III the cams y and a, projecting from the circular uprightflanges of the support 17, successively act against the rollers 1 and 2,forcing the sliding plates w and .fr in turn across the upper surface ofthe mold and folding the parallel projecting edges of the wrappingpaperover the contents. lVhile the mold is in position III, after theslidingplates are withdrawn, the stamp 3, Fig. 5, is actuated by theeccentric K upon shaft H and moves down and compresses the foldededgesof the wrapping-paper and the matter contained in the mold. Thestamp or plunger 3 is connected to its rod 4 in the same manner asheretofore described with reference to the plunger b and its shaft d.The rod 4 carries levers of the same kind as the levers g and providedwith rollers 5 and 6, which when the plunger 3 is in its lowermostposition move inwardly and engage the sliding blocks 7c, pressing thesame firmly against the contents of the mold. By this. means the matterdischarged into the mold will be well distributed and compressed by thevertical pressure of the plunger 3 and the longitudinal pressure of theblocks k under the influence of the rollers 6. When the plunger 3 andthe rollers 6 vhave receded, the work-table a. is moved into positionIV, and while moving the cam-surfaces 7 and 8, Fig. 1, act against therollers 9 and 10, forcing the verticallydisposed sliding plates 11 and12 toward each other across the end of the mold, thus folding the paperfrom the two sides of each end of the mold. As the sliding plates 11 and12 advance the blocks 7a recede from the end of the mold, such recedingmotion of the blocks k heilig obtained by means of the hinged arms 14,Fig. 5, connected to each other by a common pivot which slides up aninclined surface 13, mounted upon the frame below the table. The packageupon arriving in position IV has its upper side infolded within thepaper, and at each end the paper has been folded from both sidesinwardly, the upper and lower side of each end remaining still unfolded.The fixed support 17 of the work-table a is provided with acorresponding aperture 15, which registers with the bottom of the moldin position IV, whereby the package when placed in position IVcorresponds with said aperture 15. A forked plunger 16, carried by aprojection from the plunger-rod d, Fig. 2, and moving down with saidplunger-rod, engages the parcel between the members of said fork andforces the parcel down intothe aperture in the support 17, at the sametime folding the paper at the ends from the upper side and also causingthe edges of the aperture 15 to fold the paper from the lower sideacross the end as the parcel enters the said aperture. Thereupon theparcel is pushed out of said aperture at the lower side of the support17 completely wrapped.

If it be desired to apply a second wrapper around the same parcel, thismay be done in the following manner: A second work-table 18 is arrangedbelow the main work-table a, but eccentrically to the same, and isrotated at regular intervals corresponding with the rotation of thetable a. The said table 18 is provided with four molds I II III IV,similar to those of table a, (but without the sliding IOO blocks c,) andthe folding mechanism of said molds is the same as described withreference to the mold F of table a, Fig. 1. A blank of paper or otherwrapping material is laid on the mold in position I, and by the rstpartial rotation of the table 18it is placed below the aperture 15, andthe parcel discharged through said aperture, as before described, forcesthe paper blank into the mold and simultaneously as it enters the samemold. folding the blank into the shape of the letter U, and in itsprogress from position II into position III the cam-surfaces 20 and 2l,projecting from the upright flanges of the support for table 18, actagainst the guide-rollers of the folding-plates 22 and 23 to fold theedges of the wrapper over the other side of the parcel. Then on the wayfrom position III into position IV the cam-surfaces 26 and 27 actagainst the rollers controlling the foldingslides 24 and 25, thusfolding the paper from both sides of the two endsv of the parcel.Finally the fork 28, similar to fork 16, before described, andprojecting from the plungerrod 4, Fig. 5, engages the parcel, folds thewrapper from the upper side down, and forces the parcel through anaperture (similar to aperture 15) in the supporting-frame of the ta- IIO' of the molds and folding device of table a and.

ofthe molds and folding device of table 18 are alike the operator merelyhas to place a fresh sheet of Wrapping material upon the mold when inposition I. All further work is automatically performed by the machine,and the parcel is delivered with one wrapper from the work-table a orwith two Wrappers from the work-table 18, as may be desired, in themanner described.

Therefore, having thus fully described my said invention, what I claimas new, and desireto secure by Letters Patent, is-
